Trump retweets slew of memes, including one of him hitting Hillary Clinton with golf ball

In the latest instance of President Trump seeming to revel in the notion of physical attacks against perceived enemies, the president retweeted an animated GIF showing him hitting a golf ball that then knocks down his onetime rival Hillary Clinton.

Critics swiftly responded. Rep. Adam Schiff (D-Burbank), appearing on ABC’s “This Week, said: “It’s distressing to have a president that frankly will tweet and retweet things as juvenile as that.”

The original tweet, from a user whose Twitter handle consists of an expletive, was sent last week and retweeted Sunday by the president, who is spending the weekend at his New Jersey golf property. Here is what he retweeted:

The president has previously taken to Twitter to retweet animations including one that depicted him pummeling a figure with a CNN logo superimposed on his head. Another presidential Twitter share last month – later deleted – showed a train hitting a person, again with a CNN logo imposed on the figure’s head.

Trump associates have previously dismissed criticism of such retweets, suggesting they were intended to be humorous.

In addition to the animation taking aim at Clinton, the president retweeted a slew of other messages early Sunday. Those included a tweet criticizing a New York Times reporter, a complimentary message from a supporter and several memes containing flattering depictions of Trump.

Trump also retweeted a Bloomberg Technology article published Aug. 17 in which a financial analyst estimated that Twitter's market value would fall by up to $2 billion if the president were to stop tweeting.

A former Trump campaign strategist, David Urban, brushed aside the controversy over the Clinton GIF. “Retweets do not equal endorsements,” he said on CNN’s “State of the Union,” leading to a sharp exchange.
